Mommy Memoir: What is TMI?

Through the Storm: A Real Story of Fame and Family in a Tabloid World, by Lynne Spears reveals that Britney enjoyed cocktails at 13, lost her virginity at 14 and experimented with drugs at 15. *Jeesh, Mom, TMI much? *Anyone think Lynne revealed TMI and that maybe she could have kept some of these personal tidbits about, ahem, her daughter's life out of her cash cow book? And let's face it--after the year the Spears' sisters had, for a book to come out now, complete with family photos, you know it's going to sell. The book is said to boast that Lynne, though targeted as a bad mom who pushed her daughters into the spotlight, is actually a kind, caring mother with both Brit's and JL's best interests at heart--and I don't doubt that. I just wonder if she could have made that point sans these sensational details. I wonder how Brit (didn't she look fab at the VMAS?) feels about her first time being public record--fellow mama had a tough year, ya know?
